Dan Ariely is back with another killer TED Talk about his research! Back in March I wrote Dan Ariely: Why People Cheat, pointing to Ariely's TED Talk about his research on cheating. Well, now TED has released video from another Ariely talk, and it's equally awesome. In his lecture, Ariely describes how we make choices, and how those choices can be influenced by the design of the choice -- like whether a form's checkbox is opt-in or opt-out, or how the choice is presented visually. After seeing this lecture, I give up, I'm just gonna have to buy Ariely's book Predictably Irrational -- if it's anything like these talks, I'm sold.
